SPINNING RING.

Application med June a,

T all whom it may concern Be it known that I, SUMNER FORBES, a

citizen of the United States, and resident of Brookline, county ofNorfolk, State of Massachusetts, have invented an Improvement: inSpinning Rings, of which the following description, in connection withthe accompanying' drawing, is a specification, like characters on thedrawing representing like parts.

This invention relates to spinning rings of that type which include acasing or holder which is provided with a bearing member or lining ofself-lubricating material and an annular traveller operating within thecasing. As exemplifying spinning rin s of this type I would refer toUnited States atents No. 957,759, May 10, 1910 and No. 1,333,072. March9, 1920.

One of the objects of the present invention is to provide an improvedspinning ring of this type which is constructed so that the annular,traveller will be subjected to a minimum friction when the spinning ringis started up thereby obviating any danger that the yarn will becomebroken and providing a structure which may be successfully used forspinning even the finest yarns.

Another object of the invention is to provide an improved spinning ringof this type which is constructed with a 'novel yarn clearer arranged sothat in case the yarn does become broken the eye of the traveller willbe protected from the loose end of yarn which is extended from thebobbin. Other objects of the invention-are to improve generallyspinning' rings of this type all as will be more fully hereinafter setforth..

In order to give an understanding of my invention I have illustrated inthe drawings a selected embodiment of. the invention which will now bedescribed after which the novel features will be pointed out in theappended claims.

Fig. 1 of the drawings is a plan View of a spinning ring embodying myinvention.

support for the annular traveller indicated at 7. The under member 1 isprovided with I 1,460,751 UNITED. sTA Es PATENTOFFICE.

This base mem-' her 1 is formed with the inwardly directed the annularbead 8 and the upper member 2 of the casing has its lower end 9 shapedto snap over the bead, saidupper member 2 having the flange 10 at itsupper end which overlies the 1iner3. The liner is thus retained betweenthe flanges 10 and 5. This liner is formed with an annulartravellerreceiving recess 11 in which the traveller is received and theportion 12 of the liner overhangs the traveller The traveller isprovided with the usual stem 13 having an eye 14 at its upper end, saidstem passing up through the opening in the liner and being supportedabove the stem.

' The parts thus far described are, or may be, all as usual in spinningrings of this type and form no part of my present invention. In spinningvery fine yarns 1t sometlmes suflicient to cause breakage of the yarnand one of the objects of my present invention is to provide a structurefor reducing such friction. I accomplish this herein by giving the outerwall 1 5 of the traveller-receiving recess a scalloped formation asshown in'Fig. 2. Asa result of this construction the traveller 7 canengage the walll5 only at the separated points 16 and hence if duringthe starting up of the spinning frame the traveller isdrawn to one sideof the recess 11 it will bear against the wall 15 only atseparatedpoints and therefore much less friction will'be developed thanif the traveller had an extended bearing against the wall of the recess.

., After the spinning ring is in Operation of the'recess with thedepending portion 116' which will engage the traveller when the latteris in its raised position. This.'depending portion 116 has a-less widththan the traveller and will produce less friction than if the travellerbears against the upper face of the'recess throughout its entire width.Moreover the space outside of the depending portion 116 forms an airchamber in which the. air is given a whirling motion by the rotationofthe traveller and the presence of such rotating current of air tendsto keep the traveller free from lint. I

It sometimes happens that a yarn will break .during the spinningoperation and when this occurs with spinning rings of this typeheretofore used the loose end 17 from the bobbin 18 will fly out bycentrifugal force and will constantly strike the eye 14 thusfilling upthe eye-with lint so that before the end can be pieced up it isnecessary for the operator to clear the eye.

In order'to avoid this I have provided a protecting finger whichreceives the whip of the loose end 17 a d which protects the eye 14 fromsaid endfik i This protecting nger is indicated at. 19 and it extendsupwardly from the upper side ofthe spinning ring at an inclination inthe direction in which the bobbin rotates.

Said protecting finger 19 is long enough to extend slightly above theeye 14 and is situat'ed outside of the path of travel of said eyeso thatit does not interfere with the rotation of the'traveller. I

If, however, the yarn breaks the loose end will strike the finger 19. at.'each rotation of the bobbin and the inclination of the finger willraise the yarn up above the level of the eye as the yarn sweeps over thefinger. Upon breakage of the yarn the traveller will naturally come torest in substantially the positions shown in Figs. 1 and 4 and when inthis position the loose end 17 will be directed over the eye by thefinger 19 at each rotation of the bobbin so that the eye will not bewhipped by the loose end and there-.
